Answer 1

Answer:

figure one only

Step-by-step explanation:

Hey There!

To solve this one we are going to use the Pythagorean Theorem

The Pythagorean Theorem states that the two shorter sides squared equals the longest side squared

if this is true for the triangles then they are indeed right triangles

for figure 1...

$6^2=36\\8^2=64\\36+64=100\\10^2=100\\100=100$

this is true therefore figure 1 is a right triangle

for figure 2

$10^2=100\\12^2=144\\144+100=244\\14^2=196\\244\neq 196$

this is not true therefore figure 2 is not a right triangle

(1) is your answer :)
